- Fixed bug when enabling/disabling permanent effects in different orders than they were disabled/enabled in; this led to effects such as add_stat giving the wrong bonuses for some users with some configs.
- API: Effect#getUUID, Effect#getNamespacedKey, Player#getEffectAmount have been removed, and a new Identifiers parameter is passed to effects on enable / disable instead (A data class of a UUID and NamespacedKey to be used)
- Rewrote the entire effect scanning system (again), will be faster and more reliable now.
